abstract = {Context. Several new phenomena have arisen in the area of
study of the repeating thermonuclear explosions called
novae. For example, recurrent novae have been proven to be
efficient cosmic ray hadronic accelerators thanks to the
recent observations of RS Ophiuchi by different γ-ray
instruments. Novae have also been demonstrated to have the
ability to carve large cavities into the interstellar medium
(ISM), with parallels with the remnants of supernovae.Aims.
Our aims are to calculate the effects of novae on their
surrounding media, and the distances over which these
effects dominate over the average quantities that are
measured in the ISM.Methods. We calculated the filling
factor of novae and their contribution to cosmic ray fluxes
using cosmic ray propagation codes. To limit the atomic
density of the ISM surrounding the region of RS Oph, we used
Fermi-LAT observations of the region.Results. The filling
factor of novae in the Galaxy is not significant under all
assumptions done in the paper. They do not dominate over the
local cosmic ray fluxes, even at the lowest energies, for
distances larger than a few parsecs. The particle density of
the ISM surrounding them is, however, very much modified,
being lowered by more than one order of magnitude with
respect to galactic averages, confirming estimates done
using other observatories.Conclusions. Even though at global
galactic distances, novae do not seem to be dominating
cosmic ray transport, they have the power to modify the
conditions of their surrounding ISM over parsec distances.},
